Hamilton said XIX wanted to be at every single race and has been supportive

F1 driver Lewis Hamilton “has again launched a robust defence of his management team," XIX Entertainment, run by Simon Fuller, according to the PA. F1 Management Chair Bernie Ecclestone had said that he “was concerned that XIX's celebrity clients were distracting the former world champion.” Hamilton said, “I think this year XIX have taken a huge amount of criticism which has been massively unfair and that's a lot to do with me, my fault really.” He added, "They've wanted to be here every single race, they've been nothing but supportive. … They've never ever had any impact on my thought process of how I handle things. I've really taken that all on board myself." With hindsight Hamilton believes that “he could have used XIX far more effectively than he did and again has proposed change for the future” (PA, 12/13).
